SHANGHAI, March 20 (Reuters) - China stocks rebounded on Friday afternoon from a lacklustre morning, led by financial shares, which analysts expect to benefit from increasing bullishness about mainland markets.
The CSI300 index of the largest listed companies in Shanghai and Shenzhen rose 1.4 percent, to 3,892.57, while the Shanghai Composite Index gained 1.0 percent, to 3,617.32 points.
For the week, the CSI300 rose 7.6 percent while SSEC was up 7.25 pct, their biggest weekly gains in three months.
The CSI300 Financials subindex jumped nearly 3 percent, with brokerages CITIC Securities, China Merchants Securities and Western Securities all up more than 8 percent.
